A Custom Spring Support Was Designed Using a Metal Bellows Instead of a Spring Coil (PT&P Ref#Bellows-Spring) 10/17/2011

A custom spring support was designed using a metal bellows instead of a spring coil. The bellows was fabricated from stainless steel, because it will be used in a highly corrosive, off-shore environment. By utilizing the metallic bellows, it was much easier to customize for a short run production, produce variations of spring rate, and develop a high load-carrying capacity. An added benefit of using the bellows instead of a custom coil was that it reduced fabrication time by half. The rolled plate shown on the left is welded to the structural pipe on the platform and a riser clamp was attached on the right.
